"If you regularly need to scan the airwaves for APs and
networks, you might consider using KwiFiManager. It not only
includes some stumbling and surveying features, but it lets you
manage your Wi-Fi connections. This might not be the right tool for
a full survey, but it's convenient for quick scans. Since it serves
as your wireless manager, stumbling is always one click away.
"Once you install and run KwiFiManager, its icon showing the
signal bars and value for the current connection appears in the
system tray. To open the application, click the icon. The details
for the current connection is shown on the main screen, as you see
in Figure 2. This includes the channel, data rate, MAC address of
the AP, and your assigned IP address."
